The compliant sample preparation system ensures increment by increment size crushing from ROM ~ 150 mm to pulverization upto 72 mesh with proportionate drawal of moisture samples, air drying the samples from each increment.

The discards generated in the process are delivered back to the lot by using suitable mechanisms like discard conveyors or material discard bins. Thus, a completely automatic system provided by Insmart efficiently meets the requirement of automatically preparing representative coal samples without any human intervention.
